—In the databases application like storage and transmission, compression of audio is very necessary . The problem of decrease the data’s amount that needed to represent digital audio addressed by audio compression. It is applied for decreasing the redundancy by avoiding the unimportant duplicated data . In this paper, we have included a review on mechanisms of audio compression using diverse transform coding techniques. This paper aims to concentrate on the advantage of transform coding comparing with today’s techniques and to analyze the implementing of compression technique on audio using diverse transform coding. By using transform coding algorithm, many works have been doing to completely remove the noise from the audio or to reduce it, and have gained many good results from the work that has been researched .
